It’s destined to be the world’s largest cruise ship – when launched next year, Royal Caribbean’s US$1.24 billion Project Genesis will be 1,180 feet long, and carry 5400 passengers (6,400 at a pinch). It’s the most expensive ship in history, and it’s longer, wider and taller than the largest ocean liner ever built, (Cunard’s QM II), 43 per cent larger in size than the world’s largest cruise ship, (Freedom of the Seas) and remarkably, bigger than any military ship ever built, aircraft carriers included. In a world where choice of amenities count, Project Genesis has yet another trump card – in the the center of the ship is a lush, tropical park spanning the length of a football field and lined with balcony staterooms rising six decks high with views of the gardens below and the sky above.
